The Major Chord Family -- using 7th

You've probably heard a cocktail pianist take a simple melody and make it sound more sophisticated.

Let's see if we can do that ourselves.


When you just 7th or 6th, it sounds jazzier; less like a folk song.
Instead of a triad, we added a 4th note to some of the chords to enrich the sound.

The root notes and chord qualities (major or minor) are the same but the 4th note changes the preception of the tune.

A 4th note can be added to all 4 chord types.
